  1. Documented parameters by the student and tutor with corresponding items for ordinal and dichotomous scaled variables (examination quality, segmental analysis of left ventricular walls, eye-balling method for determination of ejection fraction). a According to the recommendations for chamber quantification from the American Society of Echocardiography [20]. Length and area of left ventricle were measured. b Volume was calculated using the formula [volume = 0.85 x Area2 / Diameter]. c Ejection fraction was calculated using the formula [[end-diastolic volume - end-systolic volume] / end-diastolic volume]
